Mining machine walking meshing system suitable for blocky mineral aggregate

Abstract

The invention relates to a mining machine walking meshing system suitable for blocky mineral aggregate. The mining machine walking meshing system comprises a track unit and a guide sliding shoe, wherein the guide sliding shoe comprises a sliding shoe body, a sliding shoe bottom plate and a sliding shoe rear plate; the sliding shoe bottom plate and the sliding shoe rear plate are detachably and fixedly connected to the bottoms of the front portion and the rear portion of the sliding shoe body correspondingly; the track unit comprises a front vertical plate, a rear vertical plate and track teeth; the bottom face and the front side face of the front vertical plate make contact with and are matched with an L-shaped groove in the guide sliding shoe, wherein a front groove opening of the L-shaped groove faces the rear upper portion; a step protruding backwards is arranged at the upper portion of the rear vertical plate; the top face of the rear vertical plate, the rear side face of the stepand the bottom face of the step make contact with and are matched with a front double-edge groove in a rear groove opening in the guide sliding shoe; a first material leaking channel is arranged belowa track tooth nest between the track teeth; and a second material leaking channel is arranged below the front vertical plate, the rear vertical plate and the track teeth. According to the mining machine walking meshing system, the adaptability of a drum type mining machine guide system to the high-hardness and high-lumpiness mineral aggregate can be improved, rapid abrasion and crushing of the guide system are avoided, and the fault handling time is short.

Description

technical field [0001] The invention relates to a walking meshing system of a mining machine, which is especially suitable for the case where the ore material is in the form of blocks, and the existing guide slide shoes are obviously worn, especially the bottom hook of the existing guide slide shoes is severely worn, and belongs to the underground mining machinery technology field. Background technique [0002] When using a drum-type mining machine to mine high-hardness mineral materials, the reaction force (especially impact) generated by cutting hard mineral materials has a great impact on the walking engagement system of the mining machine, and the larger ore size makes the mining machine walking engagement system The adaptability (the faster the contact surface wears and crushes due to eccentric loads, the worse the adaptability) is facing severe tests, such as Figure 16 The walking meshing system of the existing structure shown, when encountering the high hardness at t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a walking meshing system of a mining machine adapted to massive mineral materials, which can solve the problem of the adaptability of the walking meshing system of a drum type mining machine to mineral materials with high hardness and high lumpiness, and avoid walking meshing under such conditions. The system is quickly worn and crushed, which can greatly shorten the troubleshooting time, etc.
